AUDIO STEM IDENTIFICATION SYSTEMS AND METHODS

Abstract: methods, systems and computer program products are provided for determining acoustic feature vectors of query and target items in a first vector space, and mapping the acoustic feature vectors to a second vector space having a lower dimension. the distribution of vectors in the second vector space can then be used to identify items from the same songs, and/or items that are complementary. a mapping function is trained using a machine learning algorithm, such that complementary audio items are closer in the second vector space than the first, according to a given distance metric.
